During the first inning of the Nationals and Giants game on Tuesday night, Comcast SportsNet Bay Area’s broadcast caught a tense moment between Gio Gonzalez and Jayson Werth in the Washington dugout.

Werth walked past Gonzalez and said something that provoked Gio to turn around and start yelling back at the outfielder, causing pitching coach Steve McCatty to step in the pitcher’s way. Werth kept walking and appeared to take a seat in the corner of the dugout after the exchange.

Gonzalez was slow to cover first base on what could have been an inning-ending double play in the top of the first inning. Here’s a GIF of the confrontation between Gio and Jayson from Carmen Kiew on Twitter:

In closely-related news, the Nats are 14 games back of the Braves in the National League East standings.

Jon Heyman of FanRag Sports reports Thursday that the Orioles “are said to have begun fielding calls of interest” on superstar Manny Machado and “are close to the point of seriously weighing whether to trade him.”

You’d think it would be a no-brainer for the last-place O’s to flip Machado — an impending free agent — for prospects, but Heyman notes there is “still a question whether or not longtime Orioles owner Peter Angelos” will give the go-ahead. One person familiar with the situation put it a “50-50” likelihood. Another suggested that it would take a massive return, which, sure.

Machado entered play Thursday with a sensational .328/.405/.635 batting line, 15 home runs, and an MLB-leading 43 RBI in 49 games. It’d be a real shock if he’s still wearing an O’s uniform by the end of July.

Heyman reported previously that at least nine teams made aggressive plays for Machado this winter, including the Cubs, Phillies, Dodgers, Indians, Diamondbacks, Yankees, Red Sox, White Sox, and Cardinals. A whole lot of those teams still make sense here in late May — maybe all of them except the White Sox.
